Extent of the Ranikot Sea

Abstract

WITH reference to my preliminary note¹ on the results of work by Mr. Pinfold and myself on the Eocene beds of the Punjab Salt Range, we have now determined the fact that, of the six sections of the local Eocene, the lower three (Dhak Pass Beds, Khairabad Limestone and Patala Shales) are all of Upper Ranikot age ; the Patala Shales representing later Ranikot elements than have yet been found elsewhere. The three upper sections (Nammal Shales, Sakesar Limestone. and Bhadrar Beds) are of Lower to Middle Laki age, the unconformity between Ranikot and Laki being rather less on the Salt Range than elsewhere. Our paper on this subject, giving full palseontological details, will appear in due course as the, first part of vol. 24 (N.S.) of the Palaeontologia Indica.
